Twenty-one of 30 patients with essential mixed cryoglobulinemia (EMC) had evidence of liver involvement. The liver disease was characterized by the absence of clinical symptoms, hepatosplenomegaly, mild elevation of enzymes, abnormal BSP retention and low albumin levels. Histology, available in 12 patients, showed either chronic persistent or chronic active hepatitis or liver cirrhosis; 44% of the patients had HBsAg or HBsAb in sera and/or cryoglobulins, confirming the high frequency of exposure to hepatitis B virus (HBV) infection in EMC. However, liver lesions were similar in all patients, regardless of HBV exposure. Since other factors usually associated with chronic liver diseases were absent or apparently irrelevant, it is temptative to speculate that a 'cryoglobulinemic hepatitis' may exist as a distinct syndrome. The characteristic complement profile of the patients with EMC (low CH50 and C4, normal C3PA), not related to albumin levels, can help to differentiate this disease from chronic liver disease without cryoglobulins.

Zinc takes part in the catalytic function of many metalloenzymes. In others it plays a role in conformational stability. In zinc deficient animals protein synthesis is disturbed. Conversely zinc metabolism is influenced by protein deficiency. Zinc takes part in drug metabolism, in mobilizing vitamin A from the liver, and in a system defending the organism against free radical damage. Zinc distribution in the organism is influenced by steroid hormones and leucocytic endogenous mediators. Of the intracellular zinc only a small part is bound to metalloenzymes, most being coordinated to binding sites of nonspecific proteins. Thus the organism defends itself against conformational changes of irritable enzymes which may bind excess zinc to side chains. Zinc can protect the organism against cadmium toxicity. In the serum the smaller part of zinc is firmly bound to several specific proteins, the majority being loosely bound to albumin. Some aspects of human zinc metabolism in health and disease are reviewed. Zinc deficiency in man is rare. In Iran and Egypt a syndrome of iron and zinc deficiency associated with anaemia, hepatosplenomegaly, dwarfism, and hypogonadism is known. In wound healing and tissue repair substitution of zinc is beneficial only if a zinc deficiency exists. For purposes of long term parenteral nutrition zinc should be added to the different infusion solutions.

A 31-year-old man was admitted for investigation of proteinuria and hematuria. Physical examination on admission revealed systemic lymphoadenopathy, no hepatosplenomegaly, and ankle edema. Hemoglobin was 14.3 g/dl, platelet 21.4 x 10(4)/microliters and WBC 40,800/microliters which contained 86% mature lymphoid cells. Immunological phenotyping of peripheral lymphoid cells gave positive reactions for CD19, and CD20, and negative reaction for smlg. Urinary protein excretion was 8.3 g/dl in 24h. Serum total protein was 4.1 g/dl with albumin of 2.5 g/dl. Serum IgG was 302 mg/dl, IgA 43 mg/dl, and IgM 56 mg/dl. Renal biopsy showed characteristic features of membranoproliferative glomerulonephritis (MPGN). He was diagnosed as having nephrotic syndrome associated with B-cell chronic lymphocytic leukemia (B-CLL), and was treated with prednisolone and cyclophosphamide without effect. Therefore, he was treated with 18 MU of recombinant-alpha-2a-interferon (IFN-alpha)/day. This treatment resulted in almost normal WBC and differential counts, and urinary protein excretion of 3g in 24h 2 months later. After IFN-alpha treatment was discontinued, WBC count and the amount of urinary protein again increased. He was again treated with IFN-alpha at the dose of 9.0 MU/day three times a week, and is now well without any complaints. This is the first case report in which IFN-alpha was effective in a patient with nephrotic syndrome associated with B-CLL. We think that IFN-alpha therapy is worth trying in similar cases.

A 27-year-old female patient with alcoholic cirrhosis was reported. She was admitted to the hospital because of jaundice and ascites after heavy drinking. She had a history of drinking Japanese Sake in quantities of more than 5 go/day (900 ml/day) for 7 years. On admission, she was icteric, and had both hepatosplenomegaly and ascites. Laboratory data showed an elevation of serum transaminase and bilirubin, and a decrease in the albumin and prothrombin values. A biopsy specimen of the liver showed pericellular fibrosis, fatty change, Mallory bodies and regenerative nodules, and revealed findings compatible with alcoholic cirrhosis. A 99mTc-N-pyridoxyl-5-methyltryptophan scintigram showed hepatomegaly. On the 99mTc-phytate scintigram, the uptake of radioisotope to the liver was markedly decreased with the increased uptake to the spleen and bone marrow. Even 6 months after the onset, poor visualization of the hepatic image on 99mTc-phytate scintigram continued. This is the first report of alcoholic cirrhosis demonstrating a long-term poor visualization of the hepatic image on 99mTc-phytate scintigraphy.

Levels of vitamin A and components of its transport protein complex, retinol binding protein and prealbumin, as well as zinc and its major binding proteins albumin and alpha 2-macroglobulin were measured in plasma of ninety-one male Egyptian patients with active schistosomal infection and thirty-two healthy adult males. Patients were divided into four groups: Group I had active schistosomiasis without associated complications; Group II had schistosomiasis complicated by colonic polyposis; Group III had advanced schistosomiasis, hepatosplenomegaly and/or ascites; and Group IV had chronic salmonella septicaemia in addition to schistosomiasis. Results showed that all patient groups had subnormal levels of plasma vitamin A, retinol binding protein, prealbumin, zinc and albumin (P less than 0.005 for all parameters) but elevated alpha 2-macroglobulin (P less than 0.001) when compared to the control group. Alterations in the vitamin A transport proteins increased with schistosomal complications and were closely correlated to changes in vitamin A (P less than 0.005), but alterations of albumin and alpha 2-macroglobulin were less consistent and did not correlate with changes in zinc levels. There was a highly significant correlation, however, between plasma zinc concentrations and those of vitamin A, retinol binding protein and prealbumin (P less than 0.001 for all correlations) in all groups of patients as well as the control group. These findings indicate that the binding and transport proteins of both zinc and vitamin A were adversely affected by schistosomiasis and its various complications. Deficiencies of both zinc and vitamin A seem to be interrelated in this disease and the vitamin A transport system may be largely dependent on zinc status.

Six hundred and ninety-two cases of kala-azar were studied, all confirmed cases. Vaishali, Muzaffarpur, Samsatipur and Sitamarhi were the most affected districts of Bihar. Fever, weight loss, hepatosplenomegaly, anaemia, leucopenia and monocytes were the most commonly found features, whereas pigmentation of skin was found in only 4.48% of cases. Lymphadenopathy and voracious appetite were conspicious by their absence. Study of the incubation period of the disease showed that it may be as short as 24 h. Bone marrow study revealed hypoplastic marrow with increase in the cells of the monocytic series. Serum electrophoresis revealed reduction in albumin and rise in globulin, leading to decrease in A : G ratio. Tuberculin test was negative in the majority of the patients.

During a four-week trip to Nigeria a 54-year-old German developed a fever of 39 degrees C. Later on he had lymphadenopathy, pretibial oedema, dyspnoea and weight loss. After 16 weeks a wreath-like pale pink skin rash, increased pulse rate with pulse deficit and hepatosplenomegaly were noted. Abnormal laboratory findings were an increased blood sedimentation rate (95 mm), raised immunoglobulin M (483 mg/dl), haemoglobin of 12.0 g/dl, mean corpuscular volume of 76 fl and Borrelia IgM antibody titre of 1:512. The electrocardiogram was suggestive of myocarditis: the cardiac symptoms were controlled with digoxin and verapamil. The patient's general condition deteriorated while he was receiving antibiotic treatment with tetracycline and penicillin. Cerebrospinal fluid (CSF) showed an increased cell count (39/microliters) and albumin (0.98 g/dl). There was a mild, predominantly proximal, tetraplegia which--on the basis of electromyographic and biopsy findings--was thought to be due to polyneuritis and myositis. At this stage blood smear and CSF examination revealed Trypanosoma. He thereupon received suramin (1.0 g) and prednisolone (120 mg down to 40 mg) daily, to which melarsoprol was added after 6 days (0.5 ml up to 5.0 ml daily for 36 days). Almost all symptoms then regressed within 6 weeks.

This study was undertaken to assess the biochemical changes induced in chronic schistosomiasis and/or chronic HCV, as well as to pinpoint the most significant parameters which could be used as dependable indices for the differentiation of single and coupled infections with or without liver cirrhosis. The selected patients were allocated into 2 broad groups: GrII (Schistosomiasis) which was subdivided into 3 subgroups: GrII(a) schistosomal patients with hepatosplenomegaly; GrII(b) hepatosplenic schistosomal patients with decompensated liver cirrhosis; GrII(c) schistosomal patients with no organomegaly. GrIII (Combined) comprised 2 subgroups: GrIII(a) schistosomal-HCV infection with decompensated liver cirrhosis; GrIII(b) schistosomal-HCV infection without liver cirrhosis. For statistical comparison normal healthy subjects were taken as a reference group (Gr I). Results showed that schistosomal patients without organomegaly manifested non significant changes in all studied parameters compared to normal controls. Highly significant elevations in serum ALT, AST, ALP and GGT activities were recorded in all other subgroups but the highest levels are reported in GrIIb. AST/ALT and direct/indirect bilirubin ratios were highest in GrIIIa (1.17+/-0.26, 1.54 +/- 0.37, respectively). Serum total protein and albumin levels showed the highest reduction (33 and 59%) concomitantly with the highest increase in gamma-globulin level (75%) in GrIII(a). Blood total iron was significantly reduced in GrII(a,b) (15.6 and 12%) (8.8%) bilirubin, GGT and AST in this order are good discriminators between the different subgroups in GrII. On the other hand, ALT, AST, albumin, ALP, GGT, protein and direct bilirubin are the most significant indices to differentiate chronic schistosomiasis and the combined group with/or without liver cirrhosis.

In this paper we describe a patient with polycythemia vera (PV), who presented with hypercalcemia due to a parathyroid adenoma. In November 1999, the patient was admitted to our hospital with meteorism and constipation. Her physical examination revealed plethora and hepatosplenomegaly. Laboratory data revealed hyperparathyroidism in addition to PV: Rbc 8 x 10(6)/mm3, Hct 63.7%, serum calcium 13.4 mg/dl, serum phosphorus 1.2 mg/dl, albumin 4.25 mg/dl, and alkaline phophatase activity 433 U/l. Intact Parathyroid Hormone level (iPTH) was 376 pg/ml (n.v.12-72 pg/ml). Twenty-four hour urinary calcium excretion was higher than normal (900 mg). A parathyroid adenoma was detected with Tc-99m sesta-MIBI scanning under the left lobe of the thyroid gland and an ultrasonographic examination of the neck also supported the diagnosis. The patient was recommended for surgery. The histopathological examination confirmed the diagnosis. Postoperatively, iPTH dropped to 53.4 pg/ml at the 15 th minute and to 33.5 pg/ml at the first hour. The calcium level was 7.5 mg/dl one hour after the operation. Five days later, Hct was 40.8%. This case represents a rare association between PV and primary hyperparathyroidism, and may provide evidence for a causal link between PTH and polycythemia vera in our patient. In conclusion, this case indicates that the differential diagnosis of hypercalcemia and polycythemia vera should also include the possibility of a parathyroid tumor in addition to malignancy.

Diagnosis of tuberculosis (TB) in children is usually based on presumptions from several elements: clinical picture and course, x-rays, tuberculin test, and culture of pathology later on. TB is usually found in a child because of symptoms of primary disease, or through case-finding of a contact. TB is children is often a primary infection and may be gradual or acute in onset. Some of the symptoms of primary TB are low-grade fever, pallor, fatigue, and anorexia. The child may have erythema nodosum, a yellow module on the conjunctiva, hilar or mediastinal lymphadenopathy, a primary TB complex on the lung (3-10 mm), segmental density, or a positive PPD test. Children with pulmonary disease do not have adult-type cavity lesions, but may have a primary cavity that drains into the bronchi, mechanical complications, fistulas, or atelectasis. Acute TB often appears as meningitis. The pathognomonic signs are cerebrospinal fluid high in lymphocytes with very high albumin (0.6-2 g) and low glucose (0.4-0.2 g/l). TB organisms are rarely seen, but may be cultured. TB meningitis is also notable for choroidal tubercles, which are yellow nodules visible in the fundus. These presumptive signs, as well as increasing neurological findings, prompt immediate treatment. Children also may have acute miliary TB, marked by high fever, gastrointestinal symptoms, hepatosplenomegaly, dyspnea, cyanosis, and respiratory distress, with characteristic diffuse grainy spots on the chest x-ray. A child may have both conditions and may also have localized TB infection elsewhere. Thus, clinical findings may point to possible cultures of urine, gastric lavage, pleural fluid or biopsy, pericardial fluid, bone marrow, or ascitic fluid, any of which should be cultured to rule out other causes. The most common sites for extra-pulmonary TB are cervical nodes, spine, knee. shoulder, hip and peritoneum. Pelvic and urinary tract infections are rare in children.
