Alpha1-fetoprotein (AFP) is an alpha1-glycoprotein which can be found in high concentration during fetal development in many mammals, birds, sharks and, also, man. The alpha-fetoproteins of various species have similar physico-chemical properties and often common antigenic determinants. Differences of microheterogeneity depend on a different content of sialin-acid. During human fetal development the serum AFP concentration falls with increasing gestational age. 4-5 weeks after birth AFP can be detected usually in low serum concentrations. Using more sensitive immunulogic techniques e.g. radioimmunoassay there was shown that AFP is present in sera of normal adults in concentrations of 10-20 ng/ml. AFP serum concentrations rise physiologically during pregnancy up to 500-550 ng/ml. During fetal development liver, yolk sac and gastrointestinal tract are the major sites of synthesis. In primary liver cell carcinoma, hepatoblastoma and in teratoblastoma containing yolk sac tissue AFP synthesis rises in tumor cells; the AFP serum concentration increases above 2 microgram/ml. In patients with benign liver diseases e.g. virus hepatitis, a transient rise of AFP serum concentrations was seen. Moreover, increased levels of AFP were found in hereditary diseases e.g. congenital tyrosinemia, ataxia-telangiectasia and in the amniotic fluid in congenital nephrosis of Finnish type. AFP assay in serum is clinically important for the control of course and treatment of primary liver cell carcinoma and teratoblastoma. AFP assay in amniotic fluid is a method for the prenatal detection of neural tube defects and the fetal distress syndrome, especially.

The authors report a case of chronic aggressive hepatitis associated with persisting HBs (Australia) antigenaemic nephrosis. The disease proved to be membranous glomerulonephritis. Immune fluorescence revealed granular type IgG, IgM, C3 and HBs antigen deposits along the glomerular basement membrane. The IgA deposit was partly linear, partly granular. Subepithelial deposits were noted by electron microscopy along the glomerular basement membrane. It is supposed that the deposition in the glomeruli of HBs antigen-antibody immune complex was responsible for the diffuse membraneous glomerulonephritis.

Authors describe a case of chronic aggressive hepatitis with persistent HBs (Australia) antigenaemia and nephrosis syndrome. The renal process microscbically appeared to be membranous glomerulonephritis. By immunofluorescent method antigen deposits IgG, IgM, C3 and HBs of the granular type have been revealed on the glomerular basal membranes. Deposits of the IgA were partially of granular, partially of linear type. Electronmicroscopically on the glomerular basale membrane subepithelial deposits were seen. The results of this study indicate that in the case reported diffuse membranus glomerulonephritis occurred due to HBs antigen-antibody immuno-deposits on the glomerular basal membrane.

To focus attention on the problem of infant mortality in Lebanon, data were compiled on infant mortality from 1978 to 1986 at the American University of Beirut Medical Center. Causes of death are analyzed for 602 males and 398 females. 54.9% deaths occurred at 1 month of age and 77.4% died within the 1st year. Autopsies were performed on .7%. 37.7% of all neonatal deaths were due to neonatal diseases such as hyaline membrane disease, asphyxia neonatorum, immaturity, necrotizing enterocolitis, hemorrhage, hemolysis, meconium aspiration, and kernicterus. Better prenatal care would reduce this group, or the administration of corticosteroids to the mother 24-48 hours prior to delivery, as well as rapid resuscitation at birth and prevention of the 5 curses: hypoxemia, hypoglycemia, hypothermia, hypotension, and acidosis. Although unavailable in Lebanon, administration of surfactants through an endotracheal tube would also help. Infections constitute 25.1% of deaths; many are preventable through adequate public health measures and strict personal hygiene, i.e., diseases such as sepsis, pneumonia, meningitis, gastroenteritis, hepatitis, encephalitis, and 1-2 cases of the following: diphtheria, measles, peritonitis, tetanus, tuberculosis, cytomegalis inclusion, herpes, parathyphoid, pertussis, poliomyelitis, and shigellosis. Congenital diseases were 21.6%. In utero diagnosis could prevent some diseases and in utero treatment is possible for hydrocephalus and hydronephrosis. Screening programs postnatally could lead to treatment. 5.9% were malignancies such as leukemia, lymphoma, brain tumors, histocytosis, Wilm's tumor, Ewing sarcoma, and Hodgkin's disease. Early diagnosis is critical if mortality is to be reduced in this group, but medical advances are still needed. 2.9% are miscellaneous diseases such as poisoning, rheumatic diseases, marasmus, Reye's syndrome, nephrosis, rickets, and epilepsy. Most of these diseases are preventable, except for rheumatic inflammation of the heart. Recommended necessary steps to reduce infant mortality are: prenatal care, diagnosis and screening, intrauterine surgery; resuscitation and intensive care centers with modern equipment and trained personnel; national vaccination and screening programs; adequate public health measures and hygiene; parental education; and well-equipped hospitals to serve all regardless of income level.

A case of hypocomplementemic membranoproliferative glomerulonephritis was studied during remission of nephrosis induced by high doses of corticosteroids. Hepatitis B surface antigen (HBsAg) and immune complexes were detected in serum and glomeruli. Anti-hepatitis-B surface antibody, undetectable in serum by conventional radioimmunoassays was identified in circulating immune complexes (CIC). On two occasions, improvement in renal function coincided paradoxically with an extreme increase in serum HBsAg levels as well as with marked elevation of CIC. We suggest that, as previously observed in animal models of glomerulonephritis, extreme antigen excess may inhibit glomerular deposition of immune complexes.

A 38 years old male homosexual with active secondary syphilis presented with pure nephrotic syndrome while HBs and HBe tests were positive without clinical hepatitis. He had circulating immune complexes, IgG--IgM cryoglobulinemia and high IgA, IgM and IgE levels; the C3 and C4 complement constituents were normal. Examination of renal biopsy sections under light, fluorescent and electronic microscopy showed stage I membranous glomerulonephritis the syphilitic origin of which was confirmed by indirect immunofluorescence and by rapid cure under penicillin treatment. This case calls for the following comments: (1) glomerular deposits are extramembranous rather than subendothelial in syphilitic nephrosis, a disease now classified among circulating immune complexes diseases; (2) in the kidney, the treponema antigen can be demonstrated by indirect immunofluorescence and the anti-treponema antibody, by elution; (3) the outcome of the nephrotic syndrome is always favourable, either spontaneously or after penicillin treatment; (4) syphilis and HBs antigens are frequently associated, particularly in homosexual patients; one should be looked for when the other is discovered.

We report a patient, a 23-year-old man, who was a hepatitis B virus(HBV) carrier complicated with nephrotic syndrome. He was admitted to our hospital because of generalized edema and massive ascites. Laboratory data on admission were as follows: proteinuria 9,850 mg/day, Cr 2.7 mg/dl, BUN 73 mg/dl, albumin 1.9 g/dl, cholesterol 501 mg/dl, GOT 23 IU/l, GPT 19 IU/l, HBsAg(+), and HBeAg(222.7). Since his nephrotic symptoms were seriously complicated with renal failure, we selected steroid therapy for nephrosis preference. His renal function was improved and the urinary protein decreased immediately, but his liver function deteriorated. The renal biopsy revealed focal mesangial proliferative glomerulonephritis. Immunofluorescent examination revealed slight deposits of IgG, IgM, and C3 along the glomerular basement membrane and mesangial matrix. He was not compliant and often stopped taking the steroid therapy, thereby causing nephrosis to recur each time. After all, nephrotic symptoms have been well-controlled with cyclosporin and steroid. In spite of the seroconversion of HB virus by formation of HBe antibody, mutant HBV infection continued. The fact that liver biopsy revealed severe lymphoid infiltration at the portal area suggested chronic active hepatitis. His clinicopathologic course suggests that HBV-associated nephropathy does not always remit as there are some cases in whom hepatitis remains in an active state even after seroconversion, due to its mutant status. In these cases, the long-term prognosis of HBV nephropathy has not been defined. Further study is necessary to establish the optimal treatment for HB nephropathy in adults.

Following a previous note dealing with rickets, intestinal malabsorption, virus hepatitis and mongolism, the present paper deals with serum immunoglobulin behaviour in thymomegaly, nephrosis and response to TAB vaccination. Thymomegaly was accompanied by increases in all three Ig classes, followed by normalisation of values shortly after steroid treatment. in nephrotic proteinuria, determination of glomerular selectivity via the evaluation of IgG and transferrin clearance was of assistance with respect to prognosis and therapy. Artificial antigen stimulation of healthy and mongoloid subjects with TAB vaccine was not followed by differences in Ig class behaviour; similar stimulation of full-term and immature neonates, however, showed a rapid and frank increase in immature IgM values with respect to the non-stimulated immature subject of equal age and weight.

Simultaneous occurrence of acute nephrosis and hepatitis in secondary syphilis is rare. We report a 24-year-old man who presented with sudden onset of nephrotic syndrome, acute hepatitis, and skin lesions associated with secondary syphilis. A renal biopsy demonstrated electron-dense deposits located in the subepithelial, mesangial and intramembranous areas under electron microscopy. Light microscopy revealed a mild increase in mesangial matrix with normal glomerular cellularity. Immunofluorescent examination showed granular deposition of IgG and IgA along the glomerular capillary basement membrane without deposits of complements. These morphological changes differed from those reported previously. All, the heavy proteinuria, disturbances of liver function, and skin lesions resolved after 4-week treatment.

Although acute hepatitis and nephrotic syndrome are commonly reported as complications of tertiary syphilis, nephrotic syndrome concomitant with hepatitis in early-stage syphilis is rare. Here, we describe the case of a 46-year-old male who was diagnosed with acute liver dysfunction and nephrotic syndrome after presenting with general malaise, and who subsequently developed acute kidney injury. Laboratory examination showed alkaline phosphatase had a greater magnitude of elevation compared to alanine aminotransferase, suggesting the possibility of syphilitic hepatitis. The rapid plasmin regain test and Treponema pallidum hemagglutination assay were positive, supporting the presence of a syphilis infection. Additionally, liver biopsy examination showed infiltration of inflammatory cells into the portal area and epithelioid cell granulomas. Moreover, kidney biopsy examination by both optical and electron microscopy showed a congestion of neutrophils in the capillary vessels, structural collapse of the tubules, and subepithelial deposits under the epithelium of the glomerular endothelial cells. These pathological changes were consistent with those reported previously for early syphilitic hepatitis and nephrotic syndrome in early-stage syphilis. All the symptoms, including liver and renal dysfunction, resolved after benzyl penicillin treatment was initiated. Hence, we believe early-stage syphilis should be included in the differential diagnosis of unknown liver damage and/or nephrosis.
