A total of 126 children with chronic idiopathic thrombocytopenic purpura, including 35 splenectomized cases, were investigated in a long-term follow-up study, with regard to residual hematologic and immunologic abnormalities, complications and physical growth. Such hemorrhagic symptoms as petechiae, ecchymosis and epistaxis were still observed in about 22%-28% of the patients with a period of morbidity ranging from 3 to 15 years after onset. Residual thrombocytopenia below 150,000/microliters was found in 62% of patients within 5 years, 59% within 5 to 9 years and 57% within 10-14 years after onset. Other abnormalities were mild anemia, low serum level of IgA or IgM, positive antinuclear antibody, rheumatoid factor, and positive Coombs test in a small number of patients. Increased platelet-associated IgG was still obtained in patients with subnormal platelet counts whose morbid periods were 6 to 27 years after onset. Investigation of the patients by questionnaire revealed such complications as obesity, striae atrophicae, abdominal pain, headache, cataract, Perthes' disease, and cardiac complication in some patients. No apparent disturbances except for obesity were observed in their physical growth.

A 10-year-old boy had gait and speech disturbances 17 days after the initial symptoms of a fever, headache and cough. Four days later he was admitted to a hospital with mild disturbances of gait, speech, writing, visual acuity, left facial nerve, nystagmus and consciousness. Impairments of cranial nerves (II, III and VII), pyramidal sign and cerebellar sign were noticed. EEG showed generalized slow waves. Auditory brain stem response showed prolongation of the interval between I and V waves and poor differentiation between them. Brain CT could not find any abnormalities. Brain stem encephalitis was diagnosed. Clinical signs and symptoms continued for two weeks when steroid therapy was started and it was effective to improve the disease. He was discharged from the hospital without sequelae. Herpes simplex virus (HSV) type 1 was detected from cells in CSF on admission by fluorescence antibody method. HSV antibody titers in sera changed from 1/8 to 1/64 during three months by complement fixation test. Specific IgG and IgA by enzyme linked immunosorbent assay (ELISA) was high in CSF. Specific antibody in CSF/total antibody in CSF: specific antibody in serum/total antibody in serum for IgG and IgA classes were more than 1. Reports of mild type of HSV brain stem encephalitis seemed to be rare. Our case which was followed for several months carefully would be important to discuss.

The clinical pattern of 400 cases of brucellosis in Kuwait is presented. The disease was acute in 77 per cent, sub-acute in 12.5 per cent and chronic in 10.5 per cent of cases. Raw milk was the major source of infection. The major features on presentation, irrespective of the course of the disease, were fever, sweating, headache, rigors, arthralgia, myalgia, and low back pain. Hepatosplenomegaly was present in 41 per cent of cases and in 32 per cent neither liver nor spleen were palpable. The haematologic findings were not specific and hepatic dysfunction (shown by liver enzyme abnormalities) was common. Skeletal (26 per cent) and genital (8.5 per cent) changes and neurobrucellosis (7 per cent) were the major complications. The ELISA was the most sensitive and reliable diagnostic test especially in relation to chronic brucellosis and neurobrucellosis. ELISA allowed the determination of brucella-specific immunoglobulins (Ig)G, IgM and IgA in the CSF, and provided profiles of Ig, in sera, which were different in patients with chronic (elevated IgG and IgA) from those with acute (elevated IgM alone or IgG, IgM and IgA) brucellosis. Treatment with tetracycline, doxycycline or rifampicin gave a cure rate of over 91 per cent in acute and subacute brucellosis. Co-trimoxazole was associated with a relapse rate of 50 per cent. Two drug combinations of streptomycin and tetracycline, streptomycin and rifampicin or streptomycin and doxycycline were effective, but one of five patients with chronic brucellosis relapsed. A combination of streptomycin, tetracycline and rifampicin with or without steroids was used successfully in neurobrucellosis, septicaemic shock and subacute bacterial endocarditis.

We have prospectively evaluated the clinical and immunological features of serum sickness in 35 patients treated for bone marrow failure with anti-thymocyte globulin (ATG 15 mg/kg/day) and methylprednisolone (1 to 1.5 mg/kg/day). Twenty-one patients were treated for 10 days and 14 were treated for 28 days. Clinical evidence of serum sickness developed in 30 patients (86%) and included fever and malaise (100%), cutaneous eruptions (93%), arthralgias (67%), gastrointestinal complaints (67%), cephalgia (57%), blurring of vision (37%), arthritis, (30%) and lymphadenopathy (13%). Clinical serum sickness began on day 7 +/- 1 (X +/- S.E.M.) and lasted for 10 +/- 2 days in the 18 affected patients receiving the shorter course of ATG. In the 12 affected patients receiving the longer course of ATG, serum sickness began on day 9 +/- 1. The earliest manifestations of serum sickness were fever, malaise, and cutaneous eruptions. Cutaneous findings consisted of morbilliform eruptions (n = 19) and urticaria (n = 1) or a combination (n = 8) that lasted 10 to 14 days. Twenty-one patients (75%) developed a highly characteristic serpiginous band of erythema and purpura along the sides of the fingers, toes, palms and soles 12 to 48 hours before other symptoms of serum sickness. Biopsies of lesional skin during the course of serum sickness revealed immune deposits (IgM, IgE, IgA and C3) in dermal vasculature in 7 of 9 patients. Immunological changes that occurred during the course of serum sickness included increased serum levels of IgG, IgM, IgA, and IgE. Circulating immune complexes, as measured by the C1q-binding assay, increased from a mean value of 12% to 45% on day 13 +/- 1. Complement levels (C3, C4, and CH50) decreased 50 to 80% from their baseline levels on day 10 +/- 2. Acute phase reactants increased: erythrocyte sedimentation rate, C-reactive protein and beta-2 microglobulin. Abnormal urinalysis developed in 17 patients (57%) over the course of serum sickness and included proteinuria, hematuria and hemoglobinuria on day 10 +/- 3. Hematopoietic response occurred in 43%. All 5 patients who did not develop serum sickness recovered from bone marrow failure. Our data document the clinical and immunopathological findings in human serum sickness and suggest that the principles of antigen-antibody interaction, complement activation, and resultant inflammatory response as seen in the previous animal studies are directly applicable to studies of patients with serum sickness.

It is well known that the case of multiple myeloma shows punched-out lesions of the cranium without intracranial hypertension. In this paper a case of multiple myeloma is reported showing intracranial hypertension due to a large tumor that developed in the left parietal bone. There are only 13 case reports about cranial mass lesion of multiple myeloma since 1928. A 52 year-old female was admitted to Iwate Prefectural Isawa Hospital suffering from headache, nausea and vomiting. She had been already diagnosed as multiple myeloma and treated with chemotherapy using Cyclophosphamide, Melphalan and Prednisolone for 2 years. On admission, a large subcutaneous mass was presented on the left parietal region. Craniogram revealed large osteolytic lesion of the left parietal bone and 3 punched-out lesions of the frontal bone. CT scan revealed a large mass lesion in the left epidural space, diploe and subcutaneous space. Angiography showed avascular area. Brain scintigram showed diffuse hot area. Other skeletal bones showed no abnormality. Laboratory examination revealed high concentration of gamma-globulin and high erythrocyte sedimentation rate. Electrophoresis showed high value of immunoglobulin G; immunoglobulin assay was as follows: IgG-6000 mg/dl, IgA-150 mg/dl, IgM-410 mg/dl, IgE-0 mg/dl. Serum electrolytes were within normal limits. Urine didn't include Bence-Jones protein. The patient was diagnosed as multiple myeloma suffering from intracranial hypertension caused by large tumor which developed in the left parietal bone. On the operation, large tumor was existed in the epidural and subcutaneous space invading into the diploe but without infiltration into the dura mater or cerebral cortex.(ABSTRACT TRUNCATED AT 250 WORDS)

In 54 patients with migraine and 70 persons comprising the control group, the total complement level (CH50) was evaluated together with its C3 and C4 fraction level and the level of IgG, IgA and IgM immunoglobulins. It was found that the average C3 fraction level was significantly decreased, while the C4 fraction level and total complement activity remained in the normal range. The immunoglobulin level did not show any statistically significant alterations except for the IgA level, which was lowered in migraine patients. On this basis, i.e. lowering of the C3 fraction level with normal C4 fraction level and total complement activity and lack of elevation of IgA, it is felt that the alternative pathway of complement system may be activated in migraine.

The authors share their results from the studies on the incidence and characteristic of hypertonic syndrome in 132 patients with chronic glomerulonephritis (ChGN). In that random group, 65.1 per cent had renoparenchymal hypertension (RPH), 34.8 per cent of the patients had RPH among the patients with normal renal function, and with various degrees of chronic renal insufficiency (ChRI) - 95.4 per cent. In 69 patients, the diagnosis was confirmed by puncture biopsy, with a predomination of membranous, membranous-proliferative, IgA and endoproliferative ChGN. With the exception of IgA nephritis, RPH in the rest is found relatively often even in the absence of ChRI. The symptomatics of RPH was relatively poor--most frequently the patients complained of headache--in 48 per cent but patients with ChGN without RPH also had the same complaints--26 per cent. Complaints as dizziness, tinnitus and insomnia were rare. The hypertension was with a short duration (according to anamnestic data)--in 2/3 less than three years and 40 per cent of the patients had hypertonic crises or/and acute left cardiac insufficiency in spite of the relatively little alterations in ECG and fundus of the eye. Those were mainly patients with advanced ChRI. The authors lay stress upon the necessity of complex treatment of renal insufficiency and of hypertension with a view to the improvement of the prognosis of those patients.

Opportunistic infections of the central nervous system (CNS) in immunocompromised patients often represent a diagnostic and therapeutic challenge due to the variety of possible infectious agents causing CNS disease. We report the case of a severely immunocompromised 43-year-old woman presenting with headache, confusion, abnormal CSF findings (cell count 237/mm3 with 50% eosinophils and elevated protein), multiple contrast enhancing lesions on CT and MRI in the basal ganglia, and serologic findings compatible with latent or reactivated toxoplasmosis with high IgA and IgG antibody titers against Toxoplasma gondii in whom a final diagnosis of CNS cryptococcosis was made. This case illustrates the considerable difficulties in the differential diagnosis of opportunistic CNS infection in the immunocompromised host. We conclude from our report that (1) the diagnosis of toxoplasma encephalitis should not be based on serological findings but rather be proven by either PCR, mouse inoculation or brain biopsy, (2) CNS cryptococcosis can be associated with marked CSF eosinophilia and multiple cryptococcomas, and (3) cryptococcomas can persist on CT and MRI despite successful antifungal treatment.

The possibility of an IgE-mediated allergic mechanism in food-induced migraine remains controversial. Twenty consecutive migraine patients, 11 with food-induced migraine, 9 without, were investigated for determination and counting of immunocyte populations (IgA, IgM, IgE, IgG containing cells) by biopsies at duodenum 2 level. Conventional histology and plasmocyte populations were not significantly different between the two groups of migraine patients. This study does not support the existence of an IgE-mediated allergic mechanism in food-induced migraine.

We have previously shown that cimetidine, given concurrently for 2 weeks to patients on chronic dapsone therapy, reduced methaemoglobinaemia by inhibiting the formation of the toxic hydroxylamine metabolite of dapsone. The aim of the present study was to examine the effect of this combination on the benefit/toxic ratio of dapsone over a longer period. Eight patients (six dermatitis herpetiformis, one linear IgA disease, one folliculitis decalvans) on long-term dapsone 50-100 mg daily, took cimetidine 1.6 g daily concurrently for 3 months. At 3-weekly intervals, a clinical assessment was made, plasma dapsone and methaemoglobin were measured, and parameters of oxidative haemolysis were monitored. The dapsone level rose from 2298 +/- 849 ng/ml (mean +/- SD) at baseline to 3006 +/- 1131 ng/ml at week 3 of cimetidine (P < 0.01). This rise in plasma dapsone was sustained during cimetidine administration, falling to 2446 +/- 954 ng/ml when cimetidine was stopped (P < 0.02). The methaemoglobin fell from 5.5 +/- 2.2% (mean +/- SD) at baseline to 3.9 +/- 1.1% at week 3 (P < 0.01), and remained low until week 12, when there was a return to baseline values (P < 0.01). The haemoglobin did not change from the baseline of 12.7 +/- 0.3 g/dl (mean +/- SD), and other parameters of haemolysis were unaltered. There was a fall in the visual analogue score for headache (P < 0.05), but this was not associated with any deterioration in control of the skin disorders. Hence, long-term concurrent cimetidine results in increased plasma dapsone levels without increased haemolysis, and is accompanied by reduced methaemoglobinaemia for more than 2 months.(ABSTRACT TRUNCATED AT 250 WORDS)
